Emek and Luna came to a stream on a forest path. Two small bridges lay beside the water. The red bridge was 6 blocks long. The green bridge was 9 blocks long. The stream was 8 blocks wide. Emek and Luna compared the lengths. The red bridge was too short, but the green bridge was long enough. They chose the green bridge and crossed the stream safely.

Hint
Compare each bridge length with 8 blocks.
The stream is 8 blocks wide. Which bridge is long enough to cross the stream?
The 6-block red bridgeThe 9-block green bridgeBoth bridgesNeither bridgeCorrect! The green bridge is longer than the 8-block-wide stream.
Try again. Look for the bridge that is at least as long as the stream is wide.

Hint
Count from 6 up to 8.
The red bridge is 6 blocks long. The stream is 8 blocks wide. How many more blocks long would the red bridge need to be to reach 8 blocks?
Correct! The red bridge needs 2 more blocks to reach 8 blocks.
Try again. Count how many blocks you need to add to 6 to get 8.
Next🎉 Congrats! You got this question!
Hint
Compare 9 blocks with 8 blocks. Which number is greater?
Emek and Luna chose the 9-block green bridge for the 8-block-wide stream. Which comparison shows why it is long enough?
9 is less than 89 is equal to 88 is greater than 99 is greater than 8Correct! 9 is greater than 8, so the green bridge is long enough.
Try again. Think about which number is greater, 9 or 8.
